I too, have a certain fondness for bad guys redeeming themselves and doing something to help the good guys that makes all the difference in the end, especially if they're pretty cool and badass characters.

On the flip side, betrayals against the good guys are dang effective and can really put the protagonist(s) in a tight spot, although it's best when it happens with a character you'd never suspect. Too many times I've seen it where it was pretty obvious from the start that certain characters weren't going to be dependable for the protagonist characters. If a certain character seems condescending, pretentious, or narcissistic, that's usually a sign they'll stab someone in the back. People generally don't like those types of personalities and they don't want to see them succeed. But if they're warm and friendly and have a pretty jolly nature to them before they drop the hammer and go full evil, those get you good, especially if there's virtually nothing that gives their dark secrets and agendas away. xD

I also like cute and lovable unlikely heroes, as long as they can hold their own and have unique and unlikely traits that give them an unexpected edge. As in sure, they might (and should!) struggle when it comes to accomplishing their goals and objectives and their hopes and dreams, but they aren't completely helpless without their allies. I don't want them too powerful either, though. It has to be a good balance, kind of like you how spend attribute points in any kind of RPG character creator. They can and should be great in something, but then not so great in other things. And the things they're not so great in are what your supporting characters should be able to handle.

And lastly, powerful and seemingly unstoppable villains that are annoying, cheeky, overly-confident, have insanely good luck, and make life a living hell for the protagonists over and over again (basically, you want your Mary Sues to be the villains). You HATE them but LOVE them at the same time for being so effectively detestable. These are the kinds of villains that make stories a page-turner because you HUNGER to see them get pulverized and eat their just desserts. Sure, it's one thing to have imposing and dark villains like Darth Vader and Predator and those can be great and effective, but it's something on a whole other level if a cheeky, sugary, overly-cute and snotty character that has insane god-like powers be the real problem that makes the reader want to go full nuclear on them. xD
